Precipitation

Core concept

Precipitation occurs when water vapour in clouds condenses and becomes too heavy to remain suspended, falling as rain, snow, sleet, or hail.

How it works

Rain forms when water droplets in clouds combine and grow large enough to fall, common in warmer temperatures.

Why it matters

Snow forms when temperatures are cold enough for water vapour to freeze directly into ice crystals, falling as snowflakes.

Key detail

Precipitation patterns vary globally due to factors like latitude, altitude, ocean currents, and prevailing wind patterns, creating diverse climates.
